Red Firefish

Red Firefish   Fire Goby, Fire Fish, Fire Dartfish, or Red Fire Goby is a species of dartfish native to the Indian and Pacific oceans from the eastern coast of Africa to the Hawaiian. It is an inhabitant of reefs where it can be found at depths of from 6 to 70 metres (20 to 230 ft). It is usually found just above the bottom, facing into the current, where it awaits its prey of small invertebrates. The Firefish Goby contains a swim bladder which allows it to seem to hover in place. Like other Goby species, the Firefish Goby will often create its own burrow in the sand – sometimes these burrows are shared in a symbiotic relationship with the Pistol Shrimp. They usually have a bright yellow head, merging into a white body, gradually shading into a red-orange tail. Their dorsal fins are very long, and the fish flicks it back and forth. This is used as a signal to conspecifics. As a full grown adult, it reaches a maximum length of 9 centimeters (3 in). Adults occupy sandy burrows alone or
